District Court Takes Another Logical Step to Expand the Safe Harbor

With one paragraph in a Summary Judgment Order issued last week, the Northern District of California further expanded the patent safe harbor under 37 U.S.C. § 271(e)(1). Though not a huge leap from previous safe harbor decisions, the Order in Nevro Corp. v. Boston Scientific Corp. held that use of a patented invention in clinical trials falls within the safe harbor provision “even after the patients have completed their participation in the trial.” Docket No. 16-cv-06830 (N.D. Cal. July 2018).

In this case, Nevro sued Boston Scientific alleging infringement of its patents relating to Nevro’s Senza and HF10 spinal cord stimulation systems. The Senza is a spinal cord stimulator using high-frequency pulses rather than low-frequency, approved for marketing by FDA in May 2015 with labeling stating that the device is superior to conventional spinal cord stimulators using low-frequency therapy. Boston Scientific manufactures a competing spinal cord stimulator, the Spectra WaveWriter, as well as the Precise with Multiwave system. Nevro sued Boston Scientific for patent infringement in 2016 asserting that Boston Scientific infringed its patents covering methods for delivering spinal cord stimulation therapy at frequencies between 1.5 kHz and 100 kHz in its use of high-frequency therapy with Boston Scientific’s spinal cord stimulation devices. Both parties filed cross-motions for summary judgement with respect to these patents.

Because Boston Scientific used high-frequency spinal cord systems only in a clinical trial, the Court determined that its use of Nevro’s patented technology was protected by the patent safe harbor codified in 35 U.S.C. § 271(e). The safe harbor protects the use of patented technology in the development and approval of a drug:

It shall not be an act of infringement to make, use, offer to sell, or sell within the United States or import into the United States a patented invention . . . solely for uses reasonably related to the development and submission of information under a Federal law which regulates the manufacture, use, or sale of drugs or veterinary biological products.

Building from this safe harbor framework, Nevro v. Boston Scientific explained that use of the patented invention in a clinical trial is clearly reasonably related to the development and submission of information to FDA for device approval. Continued use of the invention after the clinical trial ends is necessarily included in the safe harbor because FDA “specifically approved a trial plan” that allowed patients to continue using the treatment protected by the safe harbor even after the relevant data for FDA submission was obtained and the trial concluded. Further, international standards for medical research require trial sponsors to allow participants to access the studied treatment even after the trial’s conclusion.

The Court here marginally extends the safe harbor to include the continued use of a patented invention even after the trial has ended and no further data will be submitted to FDA since it is still “reasonably related” to an FDA submission. This makes sense: the safe harbor is clearly intended to protect researchand encourage innovation; denying clinical trials protection from a safe harbor is therefore nonsensical. While continued use after the clinical trial may seem like more of a reach, denying such protection would preclude the continued treatment of the studied population – a consequence that would inherently deter other patients from participating in clinical trials down the line. Given the congressional intent to encourage innovation and the safe harbor cases preceding Nevro v. Boston Scientific, this result is only logical.
